From: Absolute dosimetry for FLASH proton pencil beam scanning radiotherapy
Measured and simulated dose distributions for the field 12 × 5 cm2. Depth- (a) and lateral-dose distributions (b,c). Solid circles represent the measured data, dashed curves represent the simulated data, and open squares and crosses the percentage difference between simulated and measured data using TOPAS and FLUKA, respectively. The field sizes were defined at the 90% of the isodose line. For simplification, the fields were named to the field size rounded down to the nearest integer.
